CORE FOR PLASTIC POSTS.

SPECIFICATION formingpart of Letters Patent No. 780,114, dated January17, 1905. Application filed May 27, 1904- Serial No. 210,109.

fication.

My invention relates to fence-posts, and particularly to an improvedstrengthening member or core designed to be embedded. in a cement orother artificial-stone post for bracing and strengthening the latter,and has for its objects to produce a comparatively simple inexpensivedevice of this character which will be securely anchored in the post andafford means for the attachment of the fencing wires or material to thepost.

To these ends the invention comprises the novel features of constructionand combina tion of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a sectional elevation of thepost, showing a strengthening member or core embedded therein inaccordance with my invention. Fig. Q'is a view of the core removed.Figs. 3 and 4 are views similar to Fig. 2 of cores illustrating otherforms of embodiment of the invention.

Referring to the drawings, 1 designates the body of the post molded orotherwise formed from cement or other artificial stone, and 2 thestrengthening member or core embedded therein, this being usuallyaccomplished by placing the core in a mold prior to lilling the latterwith the plastic material from which the body of the post is composed.The core 2, as illustrated in Fig. 2, comprises a plurality of rods orbody portions 3 and a series of transverse connecting members I,arranged. at uniformly-spaced intervals throughout the entire length ofthe members 3, to which they are welded or otherwise permanentlyattached. The members 4, which are composed of wire or other suitablematerial, are of substantially triangular form and serve to connect thelongitudinal rods or members 3 and to anchor the core firmly andsecurely within the body of the post against longitudinal movementrelative to the latter, the members 3 being arranged in spaced parallelrelation and disposed, respectively, at the points of the triangularmembers 4, which at each of such points are wrapped or coiled around therods 3. A suitable number of the members 4 have formed integraltherewith engaging arms or projections 5, which terminate externally ofone side face of the post and are in the form of loops produced bybending or folding the wire of the members back upon itself as the finalstep in the formation of the members 4 and wrap ping or ceiling theterminal of the wire, after backwardly folding the same, upon theadjacent rod. The loops 5 are disposed at one of the points or apices ofthe triangular members and present upon the exterior of the post eyes 6for the reception of a locking member or key 7, by which the fencingwires or fabric is attached to the post.

In Fig. 3 I have illustrated a form of core identical in constructionand operation with that above described, except that in the formation ofthe connecting and anchoring members 4c the wire from which the membersare composed is at each point or apex of the triangles simply welded tothe adjacent member or body portion 3, the wraps or coils being in thisinstance dispensed with, while the terminal of the wire, after beingfolded back upon itself in producing the extensions or loops 5, islikewise permanently secured by welding.

In Fig. 4 there is shown a form of core identical with that illustratedin Fig. 3, except that the members I are of substantially rectangularform and that four of the members or rods 3 are employed and disposedrespectively at the corners of the members 4., to which they are weldedor otherwise permanently fastened, as in the instance of the deviceshown in Fig. 2.

From the foregoing it is apparent that I produce a simple inexpensivedevice which will be strong and durable and one in which the transversemembers serve the twofold function of comiecting the longitudinalmembers and firmly anchoring the latter within the body of the post, itbeing obvious that this anchoring is especially effective owing to theconnecting members being arranged at spaced intervals throughout theentire length of the core. By having each brace member separate from theother brace members the series of members is not afiected by thebreaking of any of the projected loops Which support the fencing. Inattaining these ends I do not limit myself to the precise details hereinset forth, as minor changes may be, resorted to Without departing fromthe spirit of the invention.

Having thus described the invention, What is claimed is 1. An artificialfence-post having a core embedded therein comprising a plurality ofspaced longitudinal bars, and a series of individual cross-bracesembracing the bars and permanently connected thereto, certain of theupper braces only having looped portions pro- JOHN F.
